Referring to fig. 1, to improve the above problem, the present embodiment provides an exhaust silencer connecting device 100, which includes a mounting plate 110, two connecting rods 130 respectively fixed to the mounting plate 110 vertically, and a clamp 150 having two ends respectively connected to the two connecting rods 130, wherein the mounting plate 110 is used for being fixed to a rear leaf spring support of a front suspension, the two connecting rods 130 are arranged at an interval, and the clamp 150 is used for tightly clamping an exhaust silencer 200 and enabling the exhaust silencer 200 to be hung below the connecting rods 130.

Referring to fig. 2, fig. 3 and fig. 4, in the present embodiment, the mounting plate 110 is a sheet metal part. The mounting plate 110 is provided with an avoidance groove 111 for avoiding the rear leaf spring support of the front suspension, and the avoidance groove 111 is recessed toward the direction close to the connecting rod 130, so that the mounting plate can be better attached to the rear leaf spring support of the front suspension. The mounting plate 110 is provided with a plurality of mounting holes 113 for mounting bolts so as to be connected with the rear leaf spring support of the front suspension by bolts, which is advantageous for reducing the occupied space of the exhaust muffler connecting device 100.

In the present embodiment, the connecting rod 130 is a square steel pipe or a circular steel pipe. To ensure the connection stability, two connecting rods 130 are welded to the mounting plate 110 and perpendicular to the mounting plate 110. When the exhaust muffler connecting apparatus 100 is installed on a heavy-duty car, two connecting rods 130 are located at one side of the mounting plate 110 and are spaced apart in a horizontal direction to facilitate cooperation with the exhaust muffler 200. In other embodiments, the two connecting rods 130 may not be spaced apart from each other in the horizontal direction, i.e., they are not on the same horizontal plane, and only the requirement of stable connection of the exhaust muffler 200 needs to be satisfied.

In order to increase the coupling strength of the coupling bar 130, a reinforcing rib 132 is coupled between the coupling bar 130 and the mounting plate 110. In the present embodiment, three reinforcing ribs 132 are provided between each connecting rod 130 and the mounting plate 110. Three reinforcing ribs 132 are arranged at intervals in the circumferential direction of the connecting rod 130, one of the reinforcing ribs 132 is located below the connecting rod 130 to be able to better support the connecting rod 130, and the other two reinforcing ribs are symmetrically arranged on opposite sides of the connecting rod 130 in the horizontal direction. In this embodiment, the reinforcing rib 132 may be a triangular plate or a polygonal plate, and only needs to be arranged according to actual needs.

The exhaust muffler connecting apparatus 100 includes two bands 150, the two bands 150 are spaced apart along the length direction of the connecting rod 130 to collectively enclose the exhaust muffler 200, and both ends of each band 150 are connected to the two connecting rods 130, respectively. Specifically, band 150 is a metal band, and band 150 is a rigid structure that is bent in a substantially U-shape. In other embodiments, the band 150 can be made of other high-strength materials, and can be disposed as desired.

The two connecting rods 130 are respectively provided with a connecting hole 134, and both ends of the strap 150 respectively pass through the connecting holes 134 of the two connecting rods 130 and are fastened by bolts. In the present embodiment, each connecting rod 130 is provided with two connecting holes 134 along the length direction of the connecting rod 130, and the connecting holes 134 penetrate through the connecting rod 130 along the vertical direction. One end of each of the two bands 150 is engaged with the two coupling holes 134 of one of the coupling rods 130, and the other end of each of the two bands 150 is engaged with the two coupling holes 134 of the other coupling rod 130. The band 150 is inserted through the connecting rod 130 from the lower side of the connecting rod 130, and fastened and fixed to the upper side of the connecting rod 130 by bolts. In other embodiments, the band 150 can be fixed to the connecting rod 130 by other connecting means.

Referring to fig. 1 and 5, the exhaust muffler 200 is substantially a rectangular parallelepiped structure, and two lifting lugs 210 are respectively disposed at two sides of the upper portion thereof. One end of the lug 210 is fixed to the body of the exhaust muffler 200, and the lug 210 extends substantially in the horizontal direction. The lifting lugs 210 on both sides are symmetrically arranged. Each lifting lug 210 is provided with a through hole 212 for the strap 150 to pass through, and four lifting lugs 210 correspond to four connecting holes 134 one by one. In fixing the exhaust muffler 200, for one end of each band 150, the band 150 is first used to pass through the lug 210 of the exhaust muffler 200, and then is tightened by passing through the coupling hole 134 of the connecting rod 130 from the lower side of the connecting rod 130 upward, and the other end is similarly tightened. Therefore, when the band 150 is connected to the connecting rods 130, the band can pass through the lifting lugs 210 to fix the lifting lugs 210, and the exhaust muffler 200 can be fixed between the two connecting rods 130, so that the exhaust muffler 200 can be limited in the horizontal direction.

In addition, because the distance between the free ends of the lifting lugs 210 at the two sides of the exhaust silencer 200 is greater than the distance between the two connecting rods 130, when the belt clamp 150 is tightened, the lifting lugs 210 of the exhaust silencer 200 are located below the connecting rods 130 and abut against the connecting rods 130, and the exhaust silencer 200 can be limited in the vertical direction through the connecting rods 130 and the belt clamp 150.

It is understood that in other embodiments, only one band 150 may be provided, and in this case, to ensure the stability of the exhaust muffler 200, the band 150 has a larger width in the length direction of the connecting rod 130, so that the contact surface of the band 150 with the exhaust muffler 200 in the length direction of the connecting rod 130 is increased, thereby increasing the stability of the connection with the exhaust muffler 200.

The embodiment also provides a heavy-duty car, including leaf spring support and exhaust muffler connecting device 100 behind the front suspension, mounting panel 110 is fixed in leaf spring support behind the front suspension, and the two passes through the bolt fastening together, and the structure is more succinct, also is favorable to dwindling occupation space.

The operation principle and operation process of the exhaust muffler connecting device 100 are as follows:

the mounting plate 110 is used to be fixed to a rear leaf spring bracket of a front suspension of a heavy-duty car, the band 150 is substantially U-shaped, both ends of each band 150 respectively pass through the through holes 212 of the lifting lugs 210 on both sides of the exhaust muffler 200, and further pass through from the lower side of the connecting rod 130 to the upper side of the connecting rod 130, and the band 150 is received by using bolts. The two bands 150 are spaced apart in the longitudinal direction of the connecting rod 130 to collectively trap the exhaust muffler 200. The exhaust silencer connecting device 100 has a simple structure, and only needs to weld a square steel pipe with a connecting hole 134 on a metal plate, and then clamp the exhaust silencer 200 tightly by using the clamp belt 150 and fix the exhaust silencer below the connecting rod 130.

Exhaust muffler connecting device 100 utilizes strap 150 to hoist the muffler in connecting rod 130 below on the mount pad, with the steel pipe welding on the sheet metal component and borrow strap 150 can satisfy the assembly requirement, whole exhaust pipe muffler connecting device structure is succinct, compares with traditional bracket connecting device, and each part obtains easily, need not the mould, and manufacturing cost is lower. Meanwhile, for the whole heavy-duty automobile, the mounting plate 110 can be attached to the rear plate spring support of the front suspension, and the mounting plate and the rear plate spring support are locked together through bolts, so that the occupied space is reduced, and the arrangement and the assembly of other parts on the automobile frame are facilitated.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
